A cook who claimed she got 'tennis elbow' from preparing more than 300 meals a day at a child-care centre lost her bid for further compensation yesterday. In dismissing Wong Siu-ying's claim in the Court of First Instance, Deputy Judge Alan Wright described her as a 'person prone to exaggeration'. He also said a covert video showed her elbow was not injured as she claimed. The tape, shot in June, shows Ms Wong carrying fruit. 'This is completely at variance with her oral testimony that her condition has been such that at one stage she was unable to peel an apple and that she has been unable to carry home four apples,' Deputy Judge Wright said. 'She testified that her condition had not improved.' He was also 'unimpressed' that Ms Wong had not told doctors she had been employed as a cook elsewhere before working with the charity group Po Leung Kuk. 'She gave differing versions of the onset and state of the condition [of her elbow] at different times,' he said. 'There are real conflicts as to when or if complaints were made by her about the working environment and the nature of what may have been said.' Deputy Judge Wright dismissed the compensation claim for loss of earnings after he found the Po Leung Kuk had provided a safe working environment. The court heard Po Leung Kuk had already paid Ms Wong about $500,000 in compensation after she partly blamed her injury on an uncomfortable wok-cooking position. Ms Wong's duties involved preparing meals for 100 children and up to 14 staff every day at the Kwong Fuk Nursery in Tai Po. She claimed that she was unable to work as a cook again due to the injuries.
